Why is my blank report so many pages?

[sirius.cybernetics]

I have a CSV for a data source, the fields show in the left hand side (JasperSoft Studio), but I have nothing in my report at all, it's blank except for a static text string and a rectangle. If I press preview it generates thousands of pages (I have a lot of entries in my csv)... but WHY?! It's driving me nuts!

Here is my page so far:

Hello,

As i see you have big details band, this band  will repeat for every record in your dataset.

For resolve this issue you need change detail band height to 0, or remove it.

 

<detail>        <band height="0" splitType="Stretch"/> </detail>[/code]

That worked, but now where am I supposed to place my report data? :/

Ok, when you put in your detail band fields you will not have empty pages, you will have pages with your data

Note detail band height should be not very big (usual it same as field height), in other case you will have empty spaice after every rows.
